FILM-WINDING uncnamsu.

I To all whom it may concern:

Be itknown that I, FRANK P. J UDD, a citizen of the United States, residing at Tonawanda, in the county of Erie and State of 5 New York, have invented certain new and useful Improvements in Film-Winding Mechanism, of which the following is a specification.

The present invention relates to apparatus for windin film, so that the initial end thereof wil be available without the necessity of rewinding. It is particularly intended for receiving the film as it comes from the projecting appartus.

the provision of relatively simple and ractical means for obtaining the above en substantiall without friction and undue strain upon t e film, thereby avoiding danger of scratching,

breaking, or otherwise in'uring the same. 'In the accompanying rawings:-

Referring to Figure 1, arprojecting apparatus is disclosed, including a lantern 9 with film-carrying and operating mechanism 10 in advance thereof, said mechanism including an upperdelivery reel 11 and a lower receiving or winding mechanism designated generally by the reference numeral 12. This winding mechanism contitutes thesubject-matter of the present invention.

In the specific embodiment disclosed, a

supporting plate 13 is employed carryinga box 14 in.which is journaled,'preferably 1n ball bearings 15, the trunnion 16 of a receiv- This drum comprises a rear end wall 17 T anda cylindrical wall composed of 'ably slightly over support for the placing and directing means p 8 is a vertical sectional view I Specification of Letters Patent.

sections 18 and 19 hingedly connected, as illustrated at 20. The, section 19 is preferhalf of the cylindrical wall, and by reason of the hinge connection it can be swung outwardl the section 18 being permanently fastened to the end wall 17. The free end of the section 19 preferably overlaps the adj aoent end of the section. 18 and is normally held thereon by a spring latch 21. The free rotation of the drum is retarded by a drag or brake comprising a tubular guide. 21" in which is slidably mounted a shoe 21 that frictionally bears against the drum. This shoe is borne against by a s ring, the tension of which can be varied y an abutment screw 21 adjustably threaded into the guide 21.

The supporting plate 13 is provided below the drum with an car 22 on which is pivotally I ing head 24. This head is normally held in upright. position by a plunger 25 slidably mounted in the ear22 and urged against the rear side of the head below the pivot by. a spring 26, as shown more particularly in Figure 4. The head 24 is provided on one side with an enlargement or Lug 27 forming a guid'eway in which are slidably mounted vertical stems 28 of a standard 29. The uper end of this standard is located acent tothe lower portion of the open end of the receiving drum. One of the stems 28 is provided with a rack 30, and a gear 31 in mesh with said rack forms a part of a spring drum 32 that is journaled in a recess '33 formed in the front side of the head 24. A ball bearing 34 is'provided for this drum. The drumfas shown more Figures 2 and 4, has an ann ar recess 35 in mounted, as shown at 23, a support-- articularly in its rear side that receives. a coiled spring 36'. Oneend of this spring bears against an abutment 37 from the hea 24. The other end of the spring has a bearin against a correspondi'n abutment 38 carrie b the drum. The sai drum projects beyon knurled hand wheel 39. The arrangement is such that the spring 36 acts in a direction to force: the standard downwardly as Wlll be evident.

The head of the standard 29 is provided with aball bearing 40 in which isjournaled the gudgeon 41 of a roller 42 that extends into the drum and has spaced tread portions 43 of a yielding character that operate on the internal face 44 of the peripheral wall the head and has a 18,19 of said drum. The gudgeon 41 projects from the outer end of the standard and passes through a bracket 45, in the outer end of which is journaled one end of a flexible drive shaft 46. This shaft is geared to the gudgeon 41 by beveled gears 47. The other end of the shaft is journaled in another bracket 48 and carries a beveledgear 49 in mesh with anothergear 50 mounted on a drive shaft 51. It will thus be seen that when the shaft 51 is rotated motion will be transmitted by the flexible shaft 46 and the gearing to the roller 42. The said roller 42 may be designated as a placing roller that frictionally cooperates with the internal re ceiving surface 44 of the drum, andit will v be evident that this roller is movable toward and from the surface 44, its movement toward the said surface being effected by the spring drum, and its movement in an opposite direction being obtained by turning the hand wheel 39 in opposition to the spring 35 that actuates said drum.

The film to be wound is designated generally by the reference character A and is'directed to a point between the treads 43 of the roller 42 and the receiving surface 44. To this end a shaft 52 is journaled between its end in a ball bearing 53 in the upper end .of the standard 29 and projects on opposite sides of said standard. Fixed to the projecting ends are idlers 54 and 55, each idler having spaced toothed rims 56, the teeth being adapted to enter the usual marginal perforations of the film. It will-be noted that the two idlers are thus arranged in axial alignment and parallel to the placing roller 42. For the purpose of retaining the film upon these wheels grooved rollers 57 are employed that ride on the peripheries of the rims 56. These rollers, as shown more particularly in Figure 5, are carried on swinging arms 58 journaled on a pin 59 that extends through a swinging arm 60. The arm 60 is pivoted upon one side of the standard head, as shown at 61, and said arm 60 is adapted to be held against move'-' ment by a latch 62- that engages over its upper free end. The rollers 57 are yieldingly held against the rims 50 of the idlers 54 by springs 63 coiled about the pin 59 between the arms 58, and having their terminals 64 operating against the roller spindles.

- The operation of the apparatus as thus far described is as follows. The film as it comes from the projecting apparatus is threaded about the idlers 54, as indicated in Figures 2 and 3, being retained thereupon .by the rollers 57, and is passed between the treads 43 of the roller 42 and the internal receiving face 44 of the peripheral wall of the drum. Its end is preferably engaged beneath a clip plate 65 mounted on the inner side of'the free end of the section 19. If

now the shaft 51 is in operation the roller 42 will be driven and by reason of the frictional cooperation between said roller and the peripheral wall of the drum the latter. will be rotated in the'direction of the arrow shown in Figure 2, thereby winding the film against the inner face 44 of the drum. As the layers increase the roller will rise to accommodate the same :due to the yielding action of the spring drum. It will be understood that it is the cooperation of the roller 42 and the peripheral wall of the drum that constitutes thesole means for drawing the film into said drum, and as it is drawn the coupled idlers rotate freely and thus serve to direct the film to the drum without any sliding friction and undue strain.

In connection with this winding mechanism, a reel is employed that is preferably constructed as follows: Two circular heads 66 and 67 are employed. The head 66 has permanently mounted thereon an axial post 68, at the free end of which is located a projecting cross pin 69. It also carries an expansible hub 70, preferably a cylindrical spring, having adjacent free ends 71, and having its central portion provided with an ear 72 secured to the head 66 and post 68. The free end portions of the spring are furthermore provided on their rear sides with finger pieces 73 that are In line with an opening 74 formed in the head 66. The other head 67 is provided with a central opening 75 adapted to receive the free end of the post 68, and having notches 76 to allow the passage of the projectlng ends of the pins 69.

The head 67, as shown in Figures 2 and 3, is adapted to be placed within the drum against the rear wall 17, and may be detachably retained therein by any suitable means. Thus in the present embodiment, its periphery is received within a groove 77 formed at the juncture of the rear wall 17 and the peripheral wall 18-19 of the drum. Moreover it will be noted by reference to Figure 3 that the gudgeon 16 is provided with a recess 78 behind the opening 7 57 6 of said head 67.

Prior to the introduction of the film into the drum, the head 67 is placed therein. so that the film is wound against the face 44 of the drum in front of said head. After the film is completely wound into the drum. the other portion of the reel is attached by passing the hub into the space within the film, the free end of the post 68 entering the opening and the pins 69 passing through the notches 76 of the head 67. The said recess 78 of the gudgeon 68 allows for this, as indicated in dotted lines in Figure 3. The head 66 and post 68 are then given a slight turn so that the head 67 thus becomes locked upon the post. The section 19 of the drum wall is then unlatched and swung open,

whereuponthe assembled reel with the film thereon can be removed-the winding mechanism having been first disengaged by swinging the support and standard outwardly.

tom the foregoing, it is thought that the construction, operation and ,many advantages of the herein described invention will be apparent to those skilled in the art, without further description, and it will be understood that various changes in the size, shape, proportion and minor details of construction, may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.
